I'm using nexus one, android 2.3.4. I used terminal emulator to remove both GoogleCalendar.apk and GoogleCalendar.odex . Is there any way i can get these back? I've tried many ways I found on google or even in this forum but none works. Some of the guides werent very clear so maybe I've misdone something but I've tried these. -use adb to reinstall calendar.apk and calendarprovider.apk - use adb to copy and paste to system/app -use recovery from recovery image that i used to root the phone. If possible could anyone plz guide me step to step to solve the problem either to reinstall them or to use something else to replace. Thank you in advance.
